Blurb from the B&H page-

For audio quality, the recorder features High Definition Discrete Architecture (HDDA) microphone preamplifiers, each with a differential amplification circuit that has been optimized for sound while providing an optional +48V phantom power for use with condenser microphones.

It says the DR70 has the HDDA preamps as well, in the overview on the B & H site.

The Tascam rep has posted a couple of things about the 680mkii.  One said:  "The main audio improvement in the DR-680mkII comes from the upgraded op-amp, including better EIN (lower noise)." 

Another quote from the 680 thread:  "Somebody asked about op-amps on the mkII.
The mkII uses a better sounding op-amp compared to the mkI.   (BA2115 instead of BA4580)
Only the DR-70D has the NE5532 op-amp.

I thought I mentioned this before, but the Headphone knob is improved on the mkII as well - better taper and finer control."

Anybody know what HDDA mic preamps are?  I assume that's what they put into the HS-P82?

The HS-P82 apparently has what Tascam is calling Ultra-HDDA which are the NE5532 op amps. Interesting that the DR-70d has the same preamps as the HS-P82. No wonder people like that new little recorder.

They don't say this on the HS-P82 product page but on the USB2x2 page they mention it has the same op amps as the HS-P82 and then say it has NE5532.

I wonder if the firmware of the MKII can be installed on the original MKI, since it looks like the hardware (except the op amps) is the same -
that way we could have some of the long asked features (file counter reset) on the DR680, but Tascam decided that it was better to release a new machine instead of releasing new firmware with these features

That is an interesting question.  Unless Tascam releases it as firmware update to the 680, I wouldn't want to be the first to take a chance on it since the mkii can use the larger capacity cards which the 680 can't.

All of the DR series firmware updates are product-locked, and generally locked against downgrades.

No offense - but is it just a matter of jailbreaking?

Somebody with a dev kit for this Blackfin stuff must know...

Can the 680 be linked with the 680mkii or can you only link two of the same model?  I would think existing 680 owners would be excited if the mkii could be linked with the 680.

"Jailbreaking" only makes sense for a product series that has features that can be enabled/disabled programatically.  The mkII changes are are inter-mingled with each other, so end up being dependent on the hardware.   To make the software feature list othogonal would be more work.
We have had an Anti reverse-engineering policy for ever.  The reason is more pragmatic than philosophical.

I don't see a restriction against this in the hardware of software, should work fine.

Tom,

Thanks for dropping by and answering questions.

I'm quite likely to get one of the mkIIs
